-Lots of room for a 2-3 hr. spin. Pack a big lunch, wallet, keys, light-jacket or shirt, ball cap & sun block OR tools, pump, tire & kit +.
-Fits great, rides high between the shoulder blades but does not rub on them. Remains in place. Very comfortable.
-Water does not taste like a backyard rubber lined pool. Tube nicely flexible & mouthpiece easy to drink from. You get what you pay for.
